ESP32-CAM: what is the maximum capacity of the microSD card ?

Postby nounours18200 » Sat Feb 29, 2020 10:21 pm

Hi,

I would like to know what is the maximum capacity of the microSD card to remain fully compatible with the ESP-32 CAM specifications: 32 Gb ? more than 32Gb ?

Thank you for your reply,
Nounours

I think it's specified by file system FAT-32

Above 32GB, the card has to be formatted using exFAT filesystem.
exFAT is supported in IDF through FatFS library, but the support is disabled by default. You can try changing #define FF_FS_EXFAT 0 in ffconf.h from 0 to 1, and then rebuild the application.

I know that is like 7 years ago at least.

Today I tried with ESP-IDF v5. and after checking the wiring 2 times, it does work correctly with an SPI SD card module and a 16 GB card:

Code: Select all

I (316) example: Using SPI peripheral
I (316) example: Mounting filesystem
I (326) gpio: GPIO[10]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 0| Pulldown: 0| Intr:0 
I (336) sdspi_transaction: cmd=52, R1 response: command not supported
I (386) sdspi_transaction: cmd=5, R1 response: command not supported
I (426) example: Filesystem mounted
Name: SC16G
Type: SDHC/SDXC
Speed: 20 MHz
Size: 15193MB
CSD: ver=2, sector_size=512, capacity=31116288 read_bl_len=9
SSR: bus_width=1
I (436) example: Opening file /sdcard/hello.txt
I (456) example: File written
I (466) example: Renaming file /sdcard/hello.txt to /sdcard/foo.txt
I (476) example: Reading file /sdcard/foo.txt
I (476) example: Read from file: 'Hello SC16G!'
Same example with a 32 GB card does not work, dropping a:

sdmmc_card_init failed (0x107) error

It seems for me that an SD formatted or partitioned above 30GB is already too big to get initialized.

Recently i tested esp-idf 4.4.3 or something with SD_MMC 1/4-bits and SPI on S3 and i can use 64GB sd card with no issue:

Code: Select all

Name: SN64G
Type: SDHC/SDXC
Speed: 40 MHz
Size: 60906MB
It probably depends on sd card manufacturer and type. Also there is no need to format in exFat, its working with FATxx format.

This is a general error when the driver fails to fully initialize the card. It may happen with specific types/brands of cards, but in general the card size is not the root cause of such failure. If you tell us the vendor and the model of the card, we can try to purchase the same and debug this problem.

I've the exact same problem. My 16GB sd cards works fine but can't get 32GB sd cards to mount, keep getting sdmmc_card_init failed (0x107) error. I've filed a bug report here: https://github.com/espressif/esp-idf/issues/10542. Here is outoput of failure with verbose logging: https://gist.github.com/listout/73d0ce5 ... 5b810b0080

It would be extremely helpful if someone could help.

P.S. Tried enabling exFAT, doesn't work.

HI @ESP_igrr
And sorry for the very long delay! It's been ages I don't come back here.
The card was a SanDisk Ultra 32 GB

I'm having the same issue with a SanDisk 32GB card
Mine is a a microSDHC UHS-I card speed Class 10 A1
